To prevent issues like the one experienced in the attached issue, I added logic to strip column headers of their whitespace. Since we glean so much metadata--from column prefixes to domain from correctly IDing these columns, removing whitespace from them when reading the files is important
this was added to xlsx and json readers. since xpt are made with tooling, padded column names are not a concern. NDJSON and Dataset-JSON readers are also unaffected as their column names are derived from schema-validated "name" fields rather than raw file headers.
